Rather than building new products, you will compare AI-generated frontend implementations against real-world reference websites and determine which implementation is more accurate, robust, and well-constructed. This role is ideal for frontend or full-stack engineers with strong HTML, CSS, JavaScript, responsive design, browser DevTools, and web development fundamentals, including the ability to evaluate both how a page looks and how it is built., * 3-8 years of professional web development experience, primarily in frontend or full-stack development. * Strong command of HTML and CSS, including: + Semantic HTML + Flexbox + CSS Grid + Media queries + Responsive design + Legacy float- and table-based layouts * Strong understanding of browser rendering and frontend architecture. * Comfortable using Browser DevTools, including inspecting elements, computed styles, viewport dimensions, and interactive behavior. * Comfortable working from the command line, including extracting archives and running local development servers. * Working knowledge of JavaScript sufficient to read and understand DOM-manipulating scripts. * Ability to evaluate both modern and legacy web interfaces. * Strong written English and the ability to provide precise, evidence-based technical reasoning. * Availability for 2-3 hour contiguous work sessions, as each evaluation unit is timed. Equipment & Technical Setup You will need: * A desktop or laptop capable of displaying a 1920×1080 viewport. * A real local development environment. * Administrator access to your computer to install and run a local server. * Ability to download, extract, inspect, and run website source files locally. Tablets, Chromebooks, or locked-down devices that cannot run a local static server are not suitable for this project. Nice to Have * Previous AI evaluation, RLHF, preference labeling, or structured code-review experience. * Pixel-perfect design-to-code experience. * Accessibility expertise, including ARIA, semantic landmarks, and heading hierarchy. * Familiarity with common LLM-generated coding errors. * Experience with web scraping, website archiving, or DOM parsing. * Experience working with messy or legacy website codebases. * Multiple completed engagements on similar evaluation projects. Important Project Eligibility This opportunity is intended for practicing web developers with strong frontend skills. Backend-only, ML/data science-only, mobile-native, and DevOps-only backgrounds are not suitable for the role. Designers without coding experience and developers who have only worked within component libraries without hands-on CSS experience may also struggle with the evaluation requirements. Prior project experience: You must have completed at least one previous engagement with the platform in full. This project is not onboarding new experts without prior completed engagement experience., Ideal Candidate: A hands-on frontend engineer with strong HTML/CSS fundamentals, excellent visual judgment, browser and debugging expertise, and the ability to explain precisely why one implementation is technically and visually superior to another. ## Description * Evaluate each implementation at a 1920×1080 viewport and across required interactive states. * Compare visual fidelity, including: + Layout, spacing, and box model + Typography and text styling + Colors, borders, and visual treatments + Images and asset handling + Z-index, overflow, and positioning * Inspect the underlying HTML, CSS, and JavaScript to assess implementation quality. * Identify whether an implementation genuinely recreates the interface or relies on shortcuts such as excessive hardcoding, inappropriate absolute positioning, or screenshot-based rendering. * Test responsive behavior and identify layout defects at different viewport sizes. * Provide specific, evidence-based explanations supporting every preference. * Determine whether a task is genuinely broken or simply difficult and should still be evaluated., * Independent contractor engagement. * Fully remote. * Flexible scheduling, subject to the requirement for contiguous multi-hour work sessions. * Each evaluation unit typically takes 2-3 hours and is timed. * Projects may be extended, shortened, or concluded early depending on project requirements and performance. * Payments are made weekly based on services rendered. * H-1B and STEM OPT candidates are not currently supported. * Work will not require access to confidential or proprietary information belonging to another employer, client, or institution.
